Additionally, any peanut-containing comestible must be kept in a locked, hermetically sealed container until it is time for it to be consumed. Even then the peanut-containing comestible may be removed from the container and eaten only after a written 'Notice of Imminent Consumption' has been provided to every other person in the lunch room. Upon receipt of the 'Notice of Imminent Consumption', each person in the lunch room (whether or not said person has a peanut allergy) has the option to either stay and finish lunch, leave the lunch room so as to avoid the peanut-containing comestible, or to file a Stay of Consumption with the lunch room monitor.
If a 'Stay of Consumption' is filed by any other person in the lunch room (whether or not said person has a peanut allergy), then the child wishing to ingest the peanut-containing comestible is required to report to the 'peanut table' before breaking the seal on the container in which the peanut-containing comestible is stored. The peanut table is located in a secure area of the school which has been constructed with a separate air handling system from the rest of the building.
In reality, though, its probably easier to just NOT send your kid to school with a peanut butter sandwich.

But that is a luxury it can no longer afford, according to the Department of Education
